Save Model

This function is used to save a currently opened project (i.e. Write Operation). When a user clicks on this option, Select Directory: Write Operation form is displayed (Figure 1). There are three options to select which files are written by checking the appropriate Save Options

  • Full Write option provides a complete save of all the input files. In a big model, this option can take longer than the following options. 
  • Write All except Time Series Files option allows saving all the input files except the time series, and is quicker than Full Write option. This option is useful if the user has not made any changes to the time series.
  • If the user has only made changes to the formatting options in EFDC+ Explorer, then Save Profile option is useful. This is the quickest option of all three. As the models become bigger and bigger, the user must select the appropriate option to quickly save only relevant changes. The profile is always saved for the other save options also.

If the user only has the "*.EFDC" archive file and wants to create a set of files that EFDC needs to run that project, Full Write option must be selected to create all the required input files.
To create a new project using the existing project, use the Create New Folder button to create a new subdirectory under the currently displayed directory. All the .INP files will be copied to the new directory after the user selects OK on the Write Operation form.

The project specific settings for information/data that the EFDC model does not use (i.e. labels, plot formatting, etc.) are saved in the EFDC.EE file, which is located in the project directory. If the user wants to manually copy a complete EFDC project data set (together with all the ASCII .INP files or the binary archive file) the user should also copy all of the *.EE files. The most important EE project file is EFDC.EE file. The EFDC.EE file is an ASCII file that can be edited with any ASCII editor, though care should be taken not to corrupt the file.

The user can choose 2 format options:

  • The model is saved in EEMS 10 format, which means that the model only can be loaded/opened by EE10 and run with EFDC+ 10.
  • The model is saved in EEMS 8.5 format, which means that the model can be loaded/opened by both EE8.5 and EE10, but can be run with EFDC+ 8 only.

If the user wishes to save the model in EPA GVC Model format rather than EFDC+ model format, then this option should be selected in the Active Modules tab Model Selection frame on the main EFDC+ Explorer form. This method allows quick reformatting of the EFDC.INP file for the different models. Care must be exercised to ensure that all the parameters have the desired values when switching models.

Cross Platform Note

Note

Many users may want to use EFDC on both a PC and a UNIX based computer. When transferring the input files from the UNIX machine to the PC, the carriage control MUST be reset to the Windows/DOS carriage control.

EFDC+ Explorer has the ability to convert non-Windows/DOS carriage control to Windows/DOS, via the Toolbox or when loading the UNIX project for the first time. 
Also, the user may use one of several ASCII editors that have this capability as well.
